Chemical Structure
Description
The molecular framework of 2-(Propanesulfonyl)aniline HCl (C9H13NO2SHCl) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
2-(Propanesulfonyl)aniline HCl (CAS 76697-54-6) is a high-purity analytical reference standard with the molecular formula C9H13NO2SHCl and a molecular weight of 235.73 g/mol.
